Why MIMO technology for 5G (NR)?

Ⅰ、MIMO (Multiple Input Multiple Output) technology enhances wireless communication by using multiple antennas at the transmitter and receiver. It improves data throughput, extends coverage, improves reliability, resists interference, improves spectral efficiency, supports multi-user communications and saves energy, making it a key technology in modern wireless networks such as Wi-Fi and 4G/5G.

Ⅱ、MIMO Advantages MIMO (Multiple Input Multiple Output) is a technology used in communication systems (especially wireless and radio communications) that involves multiple antennas on the transmitter and receiver.The advantages of MIMO system are as follows:

• Data throughput enhancement:One of the main advantages of MIMO is its ability to increase data throughput. It is by using multiple antennas at both ends (transmitter and receiver), a MIMO system can send and receive multiple data streams simultaneously. This results in higher data rates, which is especially important in high-demand scenarios such as streaming HD video or online gaming.
• Extended Coverage:MIMO can improve the coverage of a wireless communication system. By using multiple antennas, the system allows signals to be transmitted in different directions or paths, reducing the likelihood of signal fading or interference. This is especially beneficial in environments with obstacles or interference.
• Increased Reliability:MIMO systems are more reliable because they can mitigate the effects of fading and interference by using spatial diversity, where if one path or antenna is jammed or faded, the other can still transmit data; this redundancy increases the reliability of the communication link.
• Greater Resistance to Interference:MIMO systems are inherently more resistant to interference from other wireless devices and the environment. The use of multiple antennas allows the use of advanced signal processing techniques such as spatial filtering, which can filter out interference and noise.
• Increased Spectral Efficiency:MIMO systems can achieve greater spectral efficiency, meaning they can transmit more data using the same amount of available spectrum. This is critical when available spectrum is limited.
• Multi-User Support:MIMO can support multiple users simultaneously through the use of spatial multiplexing. Each user can be assigned a unique spatial stream, allowing multiple users to access the network without significant interference.
• Increased Energy Efficiency:MIMO systems can be more energy efficient than traditional single antenna systems. By optimizing the use of multiple antennas, MIMO can transmit the same amount of data with lower power consumption.
• Compatibility with Existing Facilities:MIMO technology can often be integrated into existing communications infrastructure, making it a practical option for upgrading wireless networks without a complete overhaul.

MIMO (Multiple Input Multiple Output) technology offers a variety of advantages, including increased data throughput, improved coverage and reliability, immunity to interference, enhanced spectral efficiency, support for multiple users, and improved energy efficiency. These advantages make MIMO a fundamental technology for modern wireless communication systems, including Wi-Fi, 4G and 5G networks.
